Abstract: Cathodically electrodepositable resin having sufficient cationogenic sites to form, when enough of such sites are ionized, a stable aqueous dispersion, is dispersed in water with anionogen satisfying at least the requisite number of such sites for generating such stable dispersion. The anionogen is proportioned to supply as the satisfying anionic moieties C.sub.1-4 fatty acid anions and H.sub.2 PO.sub.4 --anions in a ratio of about 0.25:1 to 5:1. When such sites are from ionizable amino functionality, a mixture of carboxylic acid (preferably acetic) and orthophosphoric acid is the anionogen, and such acids are proportioned so that their primary acid hydrogens are not substantially in excess of all the ionizable base functionality present.
